Transforming to vertical

[rambler4466]

Using PS CS5 when I try to "transform" the pillars to vertical, the bottom of the right pillar moves left, this movement exposes the original pillar on the layer bellow. Is there a way to remove it other than cloning? Or how can I straighten this image without revealing a lower layer?

Hi Rambler. You should be able to select both layers before you Edit/Transform/Skew and they should then move together.

Thanks, FrankMi (from FrankDe aka rambler). I converted the Background Layer to an editable layer by double clicking on it.
Then Edit/Transform/ Skew to straighten the pillar, then I cropped out the edges to get what I was looking for. Your tip worked!

This raises an interesting question I had never really thought about before.

I would always straighten verticals by stretching the top wider, not squeezing to bottom together and that avoids the problem you had rambler4466 - btw, what is your first name?

However, then I wondered am I doing it wrong - i.e. potentially damaging my pixels more than necessary?
Which way do others correct their perspective - stretch or squeeze?

Dave, I noticed when I transformed using the top slider, less of the side was needed to crop, but the pillars on the right noticeable moved in with a slight bow. When I moved the bottom slider, the one on the lower right, in and slightly up to straighten the right pillar, the opposite bottom corner moved with it. The pillars moved slightly forward rather than bow inward. I had to crop out both corners rather than just one edge. Transforming from the bottom, therefore worked slightly better even though I had to crop both the left and right edge. It did not seem to make any difference between the skew or perspective choices.

If I return to that same location to photograph, if I center my camera position, I will not need to straighten anything!

NB. I included my first name in my profiles and when I first tried to download the image from my computer, I forgot to copy and paste. Thanks for your help.

Hi Dave! For me it depends on the image but most often I stretch. When the time comes to crop I would think that you'll lose the same amount either way unless you do something to compensate, like Puppet Warp, and you don't get very good results on images with lines using Puppet Warp.

I tend to use Lens Correction (on the custom tab, you can fix vertical/horizontal perspective). So, kinda stretch and squeeze at the same time: best/worst of both worlds. Nice part is that it works the same in both Lightroom and Photoshop.

I'll need to give that a try for comparison! Thanks Kathy!

I use the following method via the crop tool. Works OK for me.

That is a great link, Victor. Thanks.

Good Question.

I don't do this much and really can't be bothered fiddling about, so I use a free download called ShiftN. It works perfectly everytime and is dead-easy.

Yes I did use ShiftN for short time myself Chris, and it is good.

I used it when moving away from Picasa and before Elements, I don't have it now (not bothered to install on the new PC), as Elements (or CS5) can do it - but admittedly not automatically.

Cheers,

Not quite sure what you're asking to be honest, but I did this in a few seconds using the transform perspective tool ...
